"Hasn't mummy told you all about Sunday?"

"Oh yes, Maud did tell me," said Margery casually. Then she gave an innocent little smile. "Oh, I called mummy Maud," she said in pretended surprise. "I quite fought I was upstairs!"

"Do you know," Margery went on with the air of a discoverer, "you mustn't say 'prayers' downstairs. Or 'corsets.'"

"I never do," I affirmed. "Well, anyhow I never will again."

"Why mayn't you?"

"I don't know," I said sleepily.

"Say prehaps."

"Well—prehaps it's because your mother tells you not to."

"Well, 'at's a silly fing to say," said Margery scornfully.
